This is a set of 45 numbered cards featuring artwork inspired by issues of Marvel Team-Up along with a few other famous team-up battles from other comic titles.
Front of the card featured framing and titles. All art and all titles were in portrait mode. Cards sold in packs of 5 plus 1 (each pack contained a standard "Cover Card" which was not part of the officially numbered set). There were no chase sets and no known separately-distributed promo cards.
The back of the cards combined to make a 17.5" x 22.5" black and white Todd McFarlane sketch art puzzle picture.
